In late May the highways agency started work on the first motorway scheme in the north-west of the UK to use "glasphalt", a new type of asphalt containing up to 30% crushed glass. Glasphalt replaces conventional aggregate in the layer below the road surface. The equivalent of 14 million bottles will be used on a four km section of the M6 between junctions 18 and 19 in Cheshire.
The glass is crushed and screened to remove corks, caps and paper labels before being mixed with conventional aggregate and bitumen.
